叶脉

What do the veins on the leaf blade look like?

叶片上的叶脉看起来像什么？

Like most monocots, orchids generally have simple leaves with parallel veins, although some Vanilloideae have a reticulate venation.

就如同大部分的单子叶植物，兰科植物通常具有有平行脉的单叶，尽管一些香荚兰亚科植物具有网状叶脉。

Inflorescence profusely branched, umbels numerous, small, 1–2 cm across, lax; bracts 2–4, lanceolate or elliptic, 3–6 × 1–2 mm, unequal, 5–7-nerved; rays 2–5(–7), 0.5–2 cm, unequal, very slender; bracteoles 5, lanceolate or elliptic, 3–4 × 1–1.5 mm, equal, 3-nerved, apex apiculate, equaling or slightly longer than flowers; umbellules 1–1.3 mm across, 5–11-flowered; pedicels 0.5–1.5 mm.

花序大量分枝，伞形花序多数，小，1-2厘米直径，疏松；苞片2-4，披针形的或椭圆形， 3-6 * 1-2 毫米，不等长，叶脉；伞辐2-5(-7)，0.5-2厘米，不等长，非常纤细；小苞片5，披针形或者椭圆， 3-4 * 1-1.5 毫米，等长，3脉，先端具细尖，稍长或近等长花；小伞形花序1-1.3毫米直径，5-11开花；花梗0.5-1.5毫米。

I see tender green leaves are oval-shaped, the above there are many veins.

我看见叶是嫩绿色椭圆形的，上面有许多叶脉。

Leaf blade ovate-elliptic, lateral nerves abaxially prominent, pale, at ca.

叶片卵形椭圆形，侧叶脉突出，浅，在约30去中脉的°；总苞片背面的被锈色绒毛。

The results showed that the plant had the character of damp-inhabiting, the cutical on the epidermis of stem and leaf is rather thin but without wax-layer, its stomata protrude clearly on the lower surface of leaf, the rate of palisade parenchyma and spongy parenchyma is rather low and the cortex is well developed in root.

结果表明蓝靛果具有明显的湿生特征：茎、叶表皮的角质层薄，无蜡被；叶片上表皮细胞甚大，无气孔，下表皮细胞小，气孔明显突起；叶脉导管直径小，壁薄；叶肉栅栏组织/海绵组织小；根的皮层发达，富细胞间隙。

They have long, narrow parallel-veined leaves, whorled or alternate, arising at the base of the stem or along it.

百合科植物具有狭长的叶，平行叶脉，叶轮生或互生，在茎基部或沿着茎生长。

Comprising seed plants that produce an embryo with a single cotyledon and parallel-veined leaves: includes grasses and lilies and palms and orchids; divided into four subclasses or superorders: Alismatidae; Arecidae; Commelinidae; and Liliidae.

由生长单子叶胚胎和平行线状叶脉叶子的种子植物组成；包含草、百合、棕榈、兰花等；分为四个亚纲或总目；泽泻亚纲；槟榔亚纲。

Leaves grow in clusters; stipe chestnut brown, shiny ; blade pentagonal, Zhang Kuange about 5-7 cm, there are three separate base, or connected to cleft pinna feather, apical pinna nearly diamond-shaped, triangular lateral pinna, feather shaft under the lateral side of the sliver compared with the previous long, the base of one the longest; vein plume bifurcation; leaves dark green above, here are milky white or milk yellow powder.

叶簇生；叶柄栗棕色，有光泽；叶片五角形，长宽各约5—7厘米，有3片基部相连的或分离的羽裂的羽片，顶生羽片近菱形，侧生羽片三角形，羽轴下侧的裂片较上侧的长，基部1片最长；叶脉羽状分叉；叶片上面暗绿色，下面有乳白色或乳黄色粉末。

Sazanami's features are the green veins on yellowish and lancerated spring leaves.

Sazanami的特色就是春天在淡黄色叶片上的绿色叶脉。
